Brand Voice Analyzer
Analyses existing content to extract the brand's voice patterns, then scores new drafts against them.
Entry verified April 20, 2026
The short answer
Voice drift is the silent killer of content brands. This skill extracts your voice fingerprint from 5-10 existing posts, then catches when a new draft doesn't match.
When to use it
After hiring a ghostwriter. After bringing on an AI drafting workflow. Quarterly, to check your own voice hasn't drifted.
Setup
- 1
Save as ~/.claude/skills/brand-voice.md.
- 2
Point it at 5-10 canonical examples in the site's /posts or /newsletter.
- 3
Produces a .claude/voice-fingerprint.json the writer skill can load.
Example
You: Score this draft against my voice. Claude: Voice match 62/100. Drift: too corporate. Uses 'leverage' (you never do), passive voice 4x (you average 0.5x/post), hedges on claims (you're direct).

Caveats
Works best for writers with a strong, distinctive voice. Less useful for corporate or neutral styles.
